Loading and Evaluating a Trained Agent

[ChrisMcCarthyDev]

When a PrimAITE session is ran that outputs a trained PPO/A2C agent, the contents of the original training config file is copied and dumped into the session_metadata.json file. When an agent is loaded, PrimAITE extracts the training config and lay-down config from the session_metadata.json. Because of this, if the session type was a TRAIN_EVAL session (session_type: TRAIN_EVAL), the agent will go through a second round of further training before getting to the evaluation. This can be overridden by amending the session type in the metadata.json file.

1. Train an Agent

This is done by calling primaite session:

2. CD to the session output directory

3. Edit the session_metadata.json file

Edit the session_type key so that the value is EVAL

4. Run the PrimAITE Session and Load the Agent

Run `primaite session --load
